SPECIFICATION forming part of Letters Patent N0. 720,470, dated February 10, 1903.

T0 @ZZ whom, it may. concern:

Be it known that I, HENRI PAYSAN, enginebuilder, a citizen of the French Republic, residing at Paris,France, (and having post-office address 10 Rue Castagnary, Paris,) have invented certain new and useful Improvements in or Connected with Motive-Power Engines, of which the following is a specification.

This invention has for its object improvements in air and other elastic-duid motors, which consists in a method of distributing the motive power, according to which no valves are placed on the cylinder, the admission being directly eected by the governor and the exhaust mechanism being fitted in the piston of the motor and operated by a peculiar cutoff arrangement on the frame of the machine. By means of this arrangement the construc-V tion of the cylinder and motor is made very simple and economical.

In order that my invention may be clearly understood, I will describe the same with reference to the accompanying drawings, of which'- Figure 1 is a side view with partial sections of the motor. Fig. 2 is a top view of the same. Fig. 3 is a section of the cylinder and the piston, showing the position yof the exhaust valve or cock and its piston. Fig. 4 shows the attachment of the rod operating the exhaust or cock.

The motor may have, for example, two cylinders 1, the pistons of whichwork in the ordinary Way on a driving-shaft 2, carrying flywheels. The valves for the admission of the motive iuid (air) to the cylinders consist of butterfly-valves arranged in boxes 3 and having their operating-handles 4 5 connected to springs 6 6, which tend to keep the valves in their closed position. These springs 6 6 are attached tothe framing of the engine. In

. front of the'valves is the main admission-cock 7, placed between these'valves and the coinpressed air or gas reservoir or the like. The

springs 6 as soon as the handles 4 5 are released.

When the speed of the motor increases, the sleeve of the governor 1l is raised by the gear 12 13 14 15, and when the motor has exceeded a predetermined speed the pin 8 ceases to come in contact with the valve-handles 4 and 5, and the valves are kept closed for the time being.

The exhaust is arranged as follows: The piston 16 of the motor is provided witha head 17, forming a cock, and with a central opening 18, terminating beyond the head 17 in a conical nozzle 19. To the plug of the cock is secured an incurved Yrod 20, the ,shape of which is clearly shown in Figs. 1 and 3. This rod, as shown in detail in Fig. 4, is hinged at 25 to the piston and acts on the plug of the cock by the way of a stud 26 with sliding blocks. This arrangement thus allows to obtain with a very small angular movement of the rod 20 a suflicient opening of the cock. A suitable arrangement tends constantly to raise the said inclined rod 2O and to cause it to bear against a stationary roller 2l. The other extremity of this rod has pivotally attached to it a nose 22, which can engage with a similar nose 23, which is attached to the cross-head and moves with the same. On thebe'd-plate is arranged a stationary stop 24. When the piston lof the motor is at the `beginning of its forward stroke, the inclined rod 2O is in its lower position and the catches 22 23 are in engagement together. In this position, Fig. 3, the exhaust-cock on the piston is closed; When the forward stroke of the piston is about to be completed, the catch 22 on the inclined rod strikes the stationary stop 24 and is disengaged from the catch 23 on the cross-head. The rod 2O being released rises and the exhaust-cock, opens and the expanded motive iiuid escapes from the cylinder. During the backward stroke of the piston the fluid will yet escape, while the cock is gradually closed. This arrangement is exceedingly simple and avoids Athe use of ordinary valves connected to the cylinders.

Having now particularly described and as? certained the nature of my invention and in whatmanner it may be carried into effect, I declare that what I claim is- IOO In a motive-power engine, the combination the piston and to be free of each other on the with a cylinder, and a suitably-operated adbackward stroke of the piston. mission-valve therefor, of a piston operating In. testimony whereof I have hereunto set in said cylinder, a cock tted in the piston, a my hand in presence of two subscribing Wit- 5 rod connected with the said cock for operatnesses.

ing it, a catch carried by the arm, operating means for the piston, and a catch carried by HENRI PAYSAN' the operating means and adapted to operate Witnesses: the catch carried by the arm, said catches EDWARD P. MACLEAN, lo adapted to engage on the forward stroke of EMILE KLOTZ.
